< blockquote>你无法从代码文件访问，你只能通过document.getelementbyid或jquery从Javascript访问。

你可以使用Page下面的代码



字符串grp = Request.Form [txtGroupName]。ToString（）;



输入标签的HTML，你有名字标签。该名称用于上面的代码（txtGroupName）

 <   p     style   =   border-bottom：solid 1px; padding：6px    name   =  p1 >  
 <   span  >  
 <  输入    id   =  chkAllSchools     nam e   =  chkAllSchools      onclick   =  ResetCheckboxes（）;    type   = 复选框    /  >  
 <   b  > 选择所有学校<   / b  >  
 <   / span  >  
 <   / p  >  

要访问allSchools复选框（不要忘记设置名称属性）



1.对于 method =get 表单，使用C＃语句

  var  result = Request.QueryString [  chkAllSchools]; 

2.对于 method =post表单，使用C＃语句

  var  result = Request .Form [  chkAllSchools]; 

如果选中复选框，C＃将为您提供字符串on（如果在我们的情况下未设置复选框，则设置为value属性），如果未在表单上选中复选框，则结果将为null。

You cant access from code file ,you have to access from Javascript only by document.getelementbyid or jquery.

you can use Page the below code

String grp = Request.Form["txtGroupName"].ToString();

in HTML for input tag, you have name tag. That name is used in above code (txtGroupName)

<p style="border-bottom: solid 1px; padding: 6px" name="p1">
   <span>
       <input id="chkAllSchools" name="chkAllSchools"  onclick="ResetCheckboxes();" type="checkbox" />
       <b>Select All Schools</b>
   </span>
</p>

To Acces "allSchools" checkbox (don't forget to set name attribute)

1. For method="get" of form, use C# statement

var result = Request.QueryString["chkAllSchools"];

2. For method="post" of form, use C# statement

var result = Request.Form["chkAllSchools"];

If checkbox is checked C# will give you string "on" (or value attribute if set for checkbox in our case not set), and if checkbox is not checked on form you'll get null in result.
